The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept.
In a pie chart, the percentage of a category is its angle divided by the full circle (360°), multiplied by 100.
Step 2: Apply the formula.
Percentage of time in school \(=\dfrac{105}{360}\times100\approx29.17\%\), which rounds to about 30%.
Step 3: Final Answer.
The time spent in school is about 30%, so option B is correct.
